FIrst we need to know what the object is? Perhaps you mean a cone or a cylinder?
You would need to know the surface area of a cylinder if you are a factory worker at Pepsi. You would need to know the dimensions of the label, so it will fit on the can.
It depends, but in let's look at a simple example to help you see how. How would you find the surface area of a cube. Find the surface area of one of the faces and since there are six of those, multiply it by 6. For example, a 2x2x2 cube. Each face has a surface area of 4 and there are 6 of them so the total surface area is 24 units. We do the same thing with other 3d objects, but it may be harder to find the surface area of faces. In face, sometimes there are no faces and we may need calculus to find the surface area.
When asked to work out the lengths of its edges and its surface area.
You cannot. You need to know the height as well. If you know the height, the surface area, A is given by A = 2*Ï€*r2 + 2*Ï€*r*h where r is the radius and h the height.
Designers must know the volume and surface area of an object because they must know how much space the object has inside it to put mabey parts in the object and to see how much the object weighs to see if it can fit somewhere without breaking it
i dont know? dont use this for your ied do nows

Some practical real world examples why surface area is important:If you want to paint a house, you need to know the surface area to determine how much paint to buy.If you want to plant grass on a dirt lot, you need to know the surface area to determine how much grass seat to use.If you want to sew a dress, you need to know the surface area of the dress (dress size) to know how much material you need.If you want to make money mowing lawns, you need to know the surface area of the lawn to know how much to charge for the work.If you want to put carpet in a living room, you need to know the surface area of the room to know how much carpet you will need.If you are making a label for a soup can company, you will need to know the surface area of the can.
It doesn't necessarily. The parameters of the experiment need to be more thoroughly defined.
In many crafts and trades an understanding of surface and volume are quite fundamental to the practice. Consider the plastering of a building, or the quantity of frosting needed for a cake. Both need to know the area surface of the object, and also need to know the volume of the surfacing material. With more practice these will become familiar and comfortable concepts.
If you want to find the surface of something, you must first specify which shape or object you wish to find the surface of, and need to say which area you are looking for, Lateral or Total surface area. Then someone will be able to answer your question.
First you need to know the size
